Detail:
  * Added 64-bit file pointer API support, following the LFS spec v1.5
    (see Docs directory). Internally, now uses 64-bit file pointers
    exclusively. For now, the backend still limits you to 4GB-1 files, but
    clients of the C library won't need recompiling again to support larger
    files than this once they use the new API.
  * Fixed a large number of warnings produced in compilation, assembly and
    linking, many of them new and resulting from the improved checks in the
    latest toolchain.
  * Increased the maximum stream buffer size from 16MB to 1GB.
  * Added Hdr:SDFS and Hdr:SDIO to the list of headers used to build swis.h
    if they are present.
Admin:
  Verified that the new 64-bit file pointer buffering code works using a
  ROM build (since the toolchain makes extensive use of reading, writing
  and seeking internally).

Version 5.64. Tagged as 'RISC_OSLib-5_64'

* _Exit() added.
* Lots of new <math.h> functions (acosh, asinh, atanh, exp2, expm1,
  ilogb, log1p, log2, logb, scalbn, scalbln, cbrt, erf, erfc,
  lgamma, tgamma, nexttoward, fmaf). Float and long double forms
  of every function added; long double forms are included as another
  library object in the stubs rather than the shared library, as they
  just branch to the double form.
* Subnormal/NaN/infinity cases in various <math.h> functions improved.
* Added <tgmath.h>.
* Headers brought into line with CC 5.54.
* RMEnsures added to C library initialisation to try to load minimum
  CallASWI, FPEmulator, CLib. No errors reported if load fails.
* A few pointless inter-file dependencies removed to reduce minimum
  size of included ANSILib.

Version 5.46. Tagged as 'RISC_OSLib-5_46'

  Aborts now give standard error messages (Abort on Data Transfer at... etc)
  *ShowRegs now filled in after aborts
  assert(), abort(), "free failed" and standard signal handlers now use Wimp
    error boxes if in the desktop
  Postmortem button on error boxes to view the postmortem

Also, x$multiply, x$divide, __rt_sdiv, x$remainder, x$udivide, __rt_udiv and
x$uremainder optimised.

Version 5.35. Tagged as 'RISC_OSLib-5_35'

  Another getenv() bug fixed.
Detail:
  stdio.c contains a vastly improved implementation of fwrite.
  hostsys.h declares _terminate_getenv to remove build warnings.
  armsys.c contains fix to getenv() to stop Omni dying.
Admin:
  Tested on desktop machine for over a week without incident, including
    several heavy fwrite users (WebServe, C compiler)
  fwrite change is documented in Doc/fwrite
  getenv() bug is Bugzilla bug #28
